Definitions
- the present invention relates to a new masking member used to protect a part of an article from a surface treatment such as coating, plating phosphatizing, vacuum evaporation and the like. More particularly, the present invention relates to a new masking member comprising a body having a vessel form consisting of a bottom and wall(s) which extend(s) upwards from the perimeter of said bottom, with said body made of a thermoplastic foam, and an adhesive layer formed on the under surface of said body.
- said surface of said article In a case where the surface treatment is effected on the surface of an article, said surface of said article often has part(s) to be protected from said surface treatment.
- said surface of said article may have part(s) to which parts such as bolts, nuts, brackets, frames, is/are attached and said surface treatment layer may sometimes obstruct the firm attaching of said parts. Therefore, it is necessary to protect such part(s) by masking member(s) and then said surface treatment is effected on said surface of said article. After said surface treatment, said masking member(s) may be removed from said surface.
- adhesive tape has been used as a masking member to protect a part of an article from a surface treatment, such as coating, plating, phosphatizing, vacuum evaporations and the like. Namely, the adhesive tape is attached to a part of an article to protect it from said surface treatment and after said surface treatment, said adhesive tape is removed from part of said article. Said part is not affected by said surface treatment since said part was covered with said adhesive tape during said surface treatment.
- said adhesive tape as a masking member has faults.
- adhesive tape attached to the part to be protected is buried in said surface treatment layer and it is very difficult to find said buried adhesive tape and, of course, it is very difficult to remove said buried adhesive tape.
- Said improved masking member is a panel consisting of a thermoplastic foam having an adhesive layer on one side. Said masking member may be attached to a part of the surface of an article which is necessary to be protected from a surface treatment by said adhesive layer of said masking member. Said panel of said masking member may have a proper size corresponding to the part of said article which is necessary to be protected from said surface treatment.
- said panel of said masking member may be thick, said masking member is not buried in said surface treatment layer and is easily found. Nevertheless, the surface treatment layer is continuously formed over said masking member and when said masking member is removed, said surface treatment layer may obstruct the smooth removing of said masking member.
- an object of the present invention is to save trouble when the masking member is attached/removed to/from said part(s) of the surface of the article which is necessary to be protected from a surface treatment.
- a masking member comprising a body having a vessel form consisting of a bottom and wall(s) which extend(s) upwards from the perimeter of said bottom, with said body made of a thermoplastic foam, and an adhesive layer formed on the under surface of said body.
- the body of the masking member is made of a thermoplastic foam, such as a polystyrene foam, a polyethylene foam, a polypropylene foam and the like and said body may be colored by a suitable color if desired, for the purpose of selection of the specified masking member according to the part to be protected.
- a thermoplastic foam such as a polystyrene foam, a polyethylene foam, a polypropylene foam and the like and said body may be colored by a suitable color if desired, for the purpose of selection of the specified masking member according to the part to be protected.
- the body of said masking member may be produced by vacuum forming from a sheet of a thermoplastic foam, the molding of expandable thermoplastic beads, and the like.
